Christian Ryan – författare

This introduction to R for students of psychology and health sciences aims to fast-track the reader through some of the most difficult aspects of learning to do data analysis and statistics. It demonstrates the benefits for reproducibility and reliability of using a programming language over commercial software packages such as SPSS. The early chapters build at a gentle pace, to give the reader confidence in moving from a point-and-click software environment, to the more robust and reliable world of statistical coding. This is a thoroughly modern and up-to-date approach using RStudio and the tidyverse. A range of R packages relevant to psychological research are discussed in detail. A great deal of research in the health sciences concerns questionnaire data, which may require recoding, aggregation and transformation before quantitative techniques and statistical analysis can be applied. R offers many useful and transparent functions to process data and check psychometric properties. These are illustrated in detail, along with a wide range of tools R affords for data visualisation. Many introductory statistics books for the health sciences rely on toy examples - in contrast, this book benefits from utilising open datasets from published psychological studies, to both motivate and demonstrate the transition from data manipulation and analysis to published report. R Markdown is becoming the preferred method for communicating in the open science community. This book also covers the detail of how to integrate the use of R Markdown documents into the research workflow and how to use these in preparing manuscripts for publication, adhering to the latest APA style guidelines.

**Voted Wisden Cricket Monthly's best cricket book ever in 2019**WINNER, BEST CRICKET BOOK, BRITISH SPORTS BOOK AWARDS 2010_________________Golden Boy is a blistering exposé of the tumultuous Lillee/Marsh/Chappells era of Australian cricket, as viewed through the lens of flawed genius Kim Hughes._________________Kim Hughes was one of the most majestic and daring batsmen to play for Australia in the last 40 years. Golden curled and boyishly handsome, his rise and fall as captain and player is unparalleled in cricketing history. He played several innings that count as all-time classics, but it's his tearful resignation from the captaincy that is remembered.Insecure but arrogant, abrasive but charming; in Hughes' character were the seeds of his own destruction. Yet was Hughes' fall partly due to those around him, men who are themselves legends in Australia's cricketing history? Lillee, Marsh, the Chappells, all had their agendas, all were unhappy with his selection and performance as captain - evidenced by Dennis Lillee's tendency to aim bouncers relentlessly at Hughes' head during net practice.Hughes' arrival on the Test scene coincided with the most turbulent time Australian cricket has ever seen - first Kerry Packer's World Series Cricket, then the rebel tours to South Africa. Both had dramatic effects on Hughes' career. As he traces the high points and the low, Christian Ryan sheds new and fascinating light on the cricket - and the cricketers - of the times.
